The accounting department your business needs

(without the headcount)

Outsourced accounting for companies too big to DIY but not ready for a full-time hire.

We work with business owners across the U.S. who are past the DIY stage — companies with real revenue, real complexity, and zero time for books that raise more questions than they answer.

Maybe your books are months behind. Maybe they're "done" but you don't trust them. Maybe your CPA keeps bringing up the same issues every year. Whatever the starting point, we get your financials to a place where they're accurate, current, and (most importantly) useful for running your business.

We specialize in working with companies doing $1M-$6M in revenue, typically 10-40 employees, in construction, manufacturing, and multi-location services.

How We Support You

Why Flat-Fee?

A full-time bookkeeper comes with a salary, payroll taxes, benefits, and a cost that tends to increase whether or not the workload does. Hourly contractors run the meter every time you have a question. Flat-fee gives you an entire accounting function for one number you can plan around.

Our flat-fee approach means:

One predictable cost for a full accounting function, not a salary plus benefits and overhead

No meter running when you call or email

Your price doesn't spike because you had a busy month

No hiring, training, or turnover to manage

You get experienced accounting support for (often) less than the loaded cost of one full-time hire, and a number you can budget around all year.

I’m Jessica, founder of Open Book

My clients come to me when their books have grown past what they can (or want to) handle themselves. I bring the structure and attention that makes financials something you rely on, not something you avoid.

With years of experience working at a CPA firm and managing books across industries, from solopreneurs to tech startups, I know how vital accurate, organized books are for decision making and peace of mind.

I work with clients across the U.S., fully virtually.
